Power Train Problems of Cadillac XTS

Currently experiencing transmission shuddering — likely due to a torque converter issue. This was confirmed by an experienced mechanic at the dealership of Cadillac. After doing deep research I’ve learned is documented in technical service bulletins such as TSB 18-na-355 and 19-na-121. The shuddering has caused the vehicle to slow down or speed up when at cruising speeds. There were no warning lights nor messages, but I've started to experience the issue/symptoms for about a month now. Which came out of nowhere. Recently, I replaced the transmission cooler line and performed a drain and fill, but the shudder continues.

In 2019, gm released service bulletin 18-na-358 that confirms the company's knowledge of of defective parts in transmissions. I have a 2017 Cadillac Xts experiencing these symptoms and gm should be responsible for parts failing due to metal shavings. This needs to be a recall. The transmissions are not getting gas, shuddering, and stalling when accelerating. This shuddering has almost caused me to be in many accidents. The vehicle owner should not be responsible for replacing expensive parts and entire transmissions due to metal shavings stalling transmissions.

Please note gm pip5146a. . . Chatter or bind feel on turns. . . Aka transmission shudder. According to Cadillac dealer in durham, nc. The car needs it's rear differential replaced; 90,000 miles. . That is happening now. Ally, the extended warranty company, sent a technician to inspect the part. I don't know if the original part is still available. I 1st noticed the problem in fall 2019. Shop invoice, 62,187miles, reflects differential fluid & filter change which temporarily, partially mitigated the problem for a few years. It never disappeared. I am not sure what the worse case safety scenario is. I never let it get that far.

On two occasions the car would not start within approximately 10 - 15 minutes of having been turned off. After inspection the dealer found that there was an intermittent fault in the throttle body assembly (dtc code p2119 throttle closed position performance). A passenger in the courtesy car from the dealer told me he had the same problem with his vehicle, but could not recall what was diagnosed.
